While reading a medical log, a nurse talks about putting nice smelling chapstick (containing vaseline, made from petroleum) on the inside of an oxygen face mask, to make it more tolerable to children. Another person comments that vaseline, when combined with pure oxygen, can ignite explosively.
So I'm asking you metal workers out there with an O2 tank, is this possible? Can you make it happen in an experiment? Will chapstick, or petroleum jelly, ignite in the presence of oxygen in a sealed metal can without the use of an open flame or spark? (A glass or plastic container is probably not a good idea.)
Please report back here.
